the effect allows you to see a video not in the traditional linear way but distorted (warped) through time. my goal was to allow arbitrary warpings through time. what you see in one frame is not only the information of one time slice but parts of several consecutive frames merged together. to specify which parts of the resulting image resemble which slice in time you have to provide a grayscale mask. where there is a white pixel in the mask a pixel of the most current image is taken for black pixels the oldest images are used and the gray scale accounts for time in between.

» eno used my timewarp effect in one of his works. he used a radial gradient like the following to postprocess a video.
